It further comprises individually controlled electric actuators, each suitable for bringing at least one warp yarn guide heddle into one of at least four positions (N1, N2, N3, N4) defining at least three warp yarn sheds (F1, F2, F3), and means for simultaneously inserting into each of the sheds (F2, F3) other than the shed (F1) into which the weft yarns are inserted, respective warp yarn guide rods ( 31, 32 ) for forming loops or pile.
Description
Technical field
The present invention relates to a kind of single net loom (single-web loom) that is used to weave loop velvet (loop velvet) fabric, and the method that weaves described velvet stuff.Such VELVET shows looped pile (loop) and suede (pile) in the single file parallel with weft direction.
Background technology
So-called " loop velvet " loom is single net loom, and its middle longitude comprises the spinning that backing (backing) spins and is used to form looped pile or suede.This type of loom has stacked shed open (shed).The bottom shed open makes parallel to be inserted by arrow shaft (rapier), and higher shed open makes rod separately to insert, and the part warp thread will form looped pile around rod.Described rod drives by being positioned at fabric device on one side, and this device is inserted in the rod of extracting out during the once picking from fabric during a picking.Can at one end carry separately blade by being positioned at different rod that loom device on one side moves, described blade is responsible for when the rod of correspondence is drawn back looped pile being cut off, thereby forms the suede of two the end of a thread.Rod by having blade and the rod that does not have blade alternately, can produce the fabric that not only has looped pile but also have suede.
In the decoration field, tight demand has the fabric of backing effect, looped pile and suede simultaneously.The loop velvet loom make can be in the single file parallel with weft direction in conjunction with the looped pile and the suede of differing heights.
For achieving the above object, show first method with diagram among Fig. 1 and 2.This method needs four picking A, B, C and D.Article two, warp thread 1
1With 1
2With weft yarn 2 associatings, form the backing of fabric.During picking A, another warp spinning 1
3Form looped pile around rod 31, during the 4th picking D, this spins 1 afterwards
3Be incorporated in the backing of fabric.The 4th warp thread 1
4Form looped pile at rod 31 and around having the rod 32 of blade, rod 32 inserts during picking C crosses the fabric backing the 3rd.By using appropriate backing weave, for example " 4/4 " or " 2/2 ", owing to do not insert weft yarn during the second picking B and the 3rd picking C, after the second leg during the picking C 32 was inserted, beat up (beat-up) of combing portion (comb) made the second leg 32 be positioned at the first leg 31 tops.After the first leg 31 and the second leg 32 are extracted out, form the row that comprises suede P, suede P is by spinning 1
4Make, and extend away from the midplane ∏ of the backing of fabric, extended height is higher than the height of looped pile BO.The method is very ineffective, because this method needs No. four loom pickings to come production delegation looped pile and suede.
Other method comprises insertion " two iron " parts, and these parts comprise two stacked rods, and one of them is used to form looped pile, and another rod that is stacked in first leg top is used to form suede.Therefore need to form three shed opens, inserting backing weft yarn and two rods simultaneously, thereby need to use the shed forming device that warp thread can be placed in four diverse locations.Therefore need to use four position full-jacquard mechanisms, as among the EP-A-0 665 312 for example disclosed like that, use coaster (tackle) system of relative complex, clumsiness.The cost of described mechanism with and complexity it is used seldom in practice.
Provide a kind of equipment among the US-A-5 522 435, thereby this equipment is by obtaining four positions with mobile support sector in conjunction with three position jacquards.If this equipment uses with rod, so during the picking of extracting rod out, warp thread can be placed in weft yarn below or top and between described rod.During the picking of inserting rod, spinning can be placed in the suede rod above or below, or be positioned at the top of parallel.So method can not be placed in the parallel below with suede or looped pile spinning, does not manufacture the effect of backing.
In another approach, can be in conjunction with two three position jacquard attachments.The shed open of regulating first device makes it can control the looped pile spinning, makes it can control the suede spinning and regulate the second device shed open.Can not be used to form suede owing to be used for the warp thread of looped pile, vice versa, so this technical scheme has reduced the selection of weave.
Therefore, be chosen in flexibility about the weave of the existing apparatus of loop velvet loom and two aspects of productivity ratio are limited to.
